Working Wordpress popunder script
 

As title says, to popunder a cambuilder ad like a lot of tubes are doing. Can't find a working script. Thanks.

Can you just use acurax popunder plugin ?

Have you tried Gopiplus Popunder Popup?

I can't post URLs yet, it's the first result on Google under "Gopiplus Popunder Popup"

Plugins and scripts from 2013-14 no work anymore with new browsers. or not work correct - we have right now thousands mobile systems and browsers. I use this service. (ref) getpopunder.com - easy install any plugin like a Head, Footer and Post Injections add code from getpopunder and forget about problems.
Is easy also to setup a mobile or desktop ads, system os and what is important countries.
few minutes of work and you can setup a campaigns for a usa mobile users and uk desktop from one website.

This is the one I use.

I'm using "CSS & JavaScirpt Toolbox" for this/ It's very useful!
